Art-house jewellery is having a moment, with designers exploring suspended shapes and modernist lines to create standout, gallery-worthy pieces. These <b>Marcel oval hoop earrings</b> from < a href=" http://www.selfridges.com/GB/en/cat/astley-clarke/" style="text-decoration: none"><font color="black"><b>Astley Clarke</b></font></a> are inspired by the kinetic work of Alexander Calder and form part of Dominic Jones’ second collection for the brand. They’re crafted from 18ct yellow-gold vermeil, with a green malachite sphere balancing carefully at the base.
